gearman_client_context() and gearman_client_set_context() can be used to store an arbitrary object for the user.

gearman_client_set_task_context_free_fn() sets a trigger that will be called when a gearman_task_st is released.

gearman_client_timeout() and gearman_client_set_timeout() get and set the current connection timeout value, in milliseconds, for the client.

Normally malloc(3) and free(3) are used for allocation and releasing workloads. gearman_client_set_workload_malloc_fn() and gearman_client_set_workload_free_fn() can be used to replace these with custom functions. (These have been deprecated, please see gearman_allocator_t for the updated interface.

gearman_client_task_free_all() is used to free all current gearman_task_st that have been created with the gearman_client_st.

WARNING:
By calling gearman_client_task_free_all() you can end up with a SEGFAULT if you try to use any gearman_task_st that you have kept pointers too.
